Dance seems to be the ultimate frivolity. How did it become a human necessity?

Every culture dances. Moving our bodies to music is ubiquitous throughout human history and across the globe. So why is this ostensibly frivolous act so fundamental to being human? The answer, it seems, is in our need for social cohesion – that vital glue that keeps societies from breaking apart despite interpersonal differences. The French sociologist Émile Durkheim (1858-1917) theorised that ‘collective effervescence’ – moments in which people come together in some form of unifying, excitement-inducing activity – is at the root of what holds groups together. More recently, Bronwyn Tarr, an evolutionary biologist and psychologist at the University of Oxford who is also a dancer, has researched the evolutionary and neurological underpinnings of our innate tendency to bust a move. Drawing on the work of both Durkheim and Tarr, this Aeon Original video explores that unifying feeling of group ‘electricity’ that lifts us up when we’re enthralled by our favourite sports teams, participating in religious rituals, entranced by music – and, yes, dancing the night away.
